How to disable Polylang for custom widget

Hello!
My site has posts on 3 languages. Switching between languages works like a charm! Even in sidebar widgets “Recent posts” I see only posts that belongs to choosed language.

But I need to make a mixed feed, that contains posts from all languages. So how to say Polylang to NOT filter posts by language at only one widget?

P.S. I also tried to show news feed via another widget of plugin “Shortcodes Ultimate” and “MH Custom Posts [lite]” (my theme is child of MH Newsdesk lite). But situation is the same. Seems that Polylang intercepts all calls to database and filter output by selected language.
